To all whom it may concern: combination of the usual cutting-die sur- Be it known that I, NAPOLEON DU BRUL, rounded by a suction-chamber, a platen a citizen of the United States, residing at Ointhrough which the cutting-die projects and 5 cinnati, in the county of Hamilton and State which may have perforations or notches ad- 5 of Ohio, have invented certain new and usejacent to the cutting-die for exhaust of air, ful Improvements in Wrapper-Cutters, of and the beveled or recessed supportingblock which the following; is a specification. loosely fitting in the cutting-die.

My invention appertains to cigar-wrapper A further feature consists in certain means cutters in which air-suction is employed for in connection with the supporting-block for IO holding the wrapper smooth over the cuttingholding it yieldingly at or about the level of die; and my present invention relates more the top of the cutting-die and for easily and particularly to the construction of the supaccurately guiding it in its up-and-down porting-platen within the cutting-die, which movement in the cutting-die when yielding I shall term the supportingblock. This to the roller or equivalent pressure device 1-5 I form without perforations, so that the wrappassed over the cutting-die to cut the wrapper. per is prevented from becoming dried out by In order that my invention may be fully the current of air which is employed to hold understood, I will proceed to describe the itsmooth. This supporting-block is cutaway same with reference to the accompanying at its periphery, so as to provide it with a drawings, in which 2o bevel or recess at its upper edge to form a Figure l is a plan view, Fig.- 2 a vertical depressed seat for the edges of the leaf, and longitudinal section, and Fig. 3 a vertical it is fitted loosely within the cutting-die, so transverse section, of the portion of awrapthat when suction is applied the wrapper will per cutter to which my invention is applied. be held all around its edges and thus enable Figs. 4 and 5 are modifications of the sup- 2 5 the bunch to be rolled in the wrapper on the porting-block.

These sleeves are provided with heads 13, which fit transversely in the slots 14 in the support 1, but which may be adjusted longitudinally in said slots to afford convenience in setting up the parts and prevent binding of the rods within their guides. Said sleeves are further provided with flanges 15, which cover the slots and prevent the admission of air to the suction-chamber 2. Rods 10 are provided at the bottom with nuts 16, threaded to the ends of said rods, and washers 17, and thereby adapted to adjust the vertical position-of the block 7.

\Vhile it may be desirable to employ a perforated outer platen 3, this is by no means essential, as the functions of the novel featu res of my device will be equally well served when said novel features are used in connection with a tight outer platen.

The advantage of the non-perforated supporting-block is that it prevents drying out of the tobacco-leaf, which causes breaking of the wrapper, and the bevel edge causes the air to be exhausted from beneath the edges of said Wrapper after it is cut, so that the wrapper will be held in position by its edges until it is removed for wrapping about the bunch. I

Whether the supporting-block be beveled, as shown in Figs. 1, 2, and 3, or rabbeted, as shown in Fig. 4:, or concaved, as shown in Fig. 5, it will be seen that in either case the edge is cut away, so as to form substantially the same construction, and I do not therefore limit myself to any particular way of cutting away the edge.

Having thus described my invention, what 1.
